After a while of using my computer everything begins to lag, even navigating windows or using my internet browser. I've scanned for viruses and I can't imagine what it would be to do with my operating system; so I believe it must be a hardware issue, because it came out of nowhere.
While playing a game called Minecraft, the game is running poorly but I brought up the task manager and it doesn't seem to be stressed.
What could be wrong with my computer that is making it lag?
Is it overheating? Here are my temps from being in Minecraft for about 10 minutes.

AMD Athlon 64 X2 Dual Core Processor 6000+ 3.1GHz, 2.00 GB of RAM, ATI Radeon HD 4830

Your CPU is overheating, your specs show the maximum temperature is 62 degrees http://products.amd....ail.aspx?id=451
I suggest taking the side off the case and check that all fans are working correctly especially the CPUs.
Take the opportunity to clean out any heat trapping dust, if you use canned compressed air do not allow the fans to spin, hold them with something like a clean Popsicle stick, remember to remove the power cord from the wall and take anti static precautions before touching anything inside the case, you can do this by touching a bare metal part of the case, once you are all back together download and run speedfan from here http://www.almico.com/sfdownload.php

I cleaned all the dust out of my computer with a compressor. Right now I'm idling at 45 - 50c, when I opened up minecraft it crawled up a bit and then my computer froze (and was still laggy). Not sure if anything is even wrong anyone.

The paste on my CPU is a bit smudged and a couple years old, what should I do about that?

Is it rude to just ask questions about my computer here?

I have one large fan that is on the High setting (It seems to run sorta slow)

Here is a picture of my computer

Did you remove the ATI Radeon HD 4830 and the Ram sticks and clean out their slots.

Clean off the existing thermal paste and apply a fresh amount, this is always the best approach
should you remove the HS and CPU fan as the paste can become contaminated with dust and you will
not get a perfect mating surface between the CPU and HS.

Not at all, we are all learning whilst helping others, thats one of the benefits of this forum.

Did you download and run Speedfan? If not do so and post a screenshot of the result.
In the Speedfan control panel try disabling the Autodetect facility and manually set all fans to 100%.
Another possibility is the gfx card, download and run (no install is necessary) gpu-z from here http://download.cnet...4-10788513.html this will provide you with info on your video card.
Also check for any driver updates for the card but hold off installing them until you have done the above.
